19-104 CERCETĂRI PRIVIND STUDIUL VIBRAŢIILOR MECANICE CU SISTEME DE ACHIZIŢII DE DATE

RESEARCH ON STUDY MECHANICAL VIBRATIONS
WITH DATA ACQUISITION SYSTEMS
The paper presents a new study method of mechanic vibrations with
the help of the data acquisition systems. The study of vibrations with the help of
data acquisition systems allows the solving of some engineering problems
connected to the measurement of some parameters which are difficult to
measure having in view the improvement of the technical performances of the
industrial equipment or devices.

20-68 INFLUENŢA IMPURITĂŢILOR METALICE ÎN PRACTICA ZINCĂRII ACIDE CU CLORURI

THE INFLUENCE OF METAL IMPURITIES
IN CHLORIDE ACID ZINC COATING
The paper present the some defects caused by impurities, acid zinc
coating occurred in practice, defects can be fixed depending on the nature of
the case, reversible reactions, or the time of referral. Conclusions drawn from
the study of the influence of metal impurities. Like all plating baths, acidic
galvanizing bath is very sensitive to metal pollution and aggressive foreign
electrolyte greatly increases the risk of such pollution. Particular attention
should be given to measures to avoid the intake of foreign metal galvanizing
bath and their immediate disposal, where their presence is found.
